ET’s Leanne Aguilera caught up with Deeley at Lifetime's Television Critics Association press day, where she was promoting her new series, This Time Next Year. Deeley couldn't have been more excited by her pregnancy, though admitted that she hadn’t wanted to spill the beans so soon.

“I’m very excited! I’m very, very good. I feel all good, actually,” the 41-year-old actress told ET. “To make announcements is not really me, but I just thought, ‘Oh, I can’t spend three hours of my life on Sunday sucking in.’”

Deeley also explained that it's important to her that her son, Milo, have a brother or sister.

“I’m very, very close to my brother and so I’m really happy that Milo will have a sibling too,” she dished. “So, we’re just delighted and excited and all those things.”

Milo isn’t really aware that he’s no longer going to be an only child, however.

“He’s only two,” she explained. “He’s a chatter, and he does understand things, but no, we haven’t explained it to him yet. I don’t know if he’s going to like it at first. He might not. He’s used to being the center of the universe, so we’ll see. But I think he’ll really enjoy it later on.”

Deeley noted that she and Kielty don’t plan to learn the baby’s gender before the birth.

“I don’t think we will, because it doesn’t matter to us really,” she said. “We’re just excited either way. As long as the baby is healthy, I think all any mom or dad wants for their child is for them to be happy. So as long as they’re healthy, we don’t mind.”

Deeley added that her pregnancy has been smooth thus far as she prepares to welcome her second child in the spring.

“I’m really lucky. I have really good pregnancies. I don’t feel too ill. You always feel a bit tired to begin with, but then I’m kind of fine,” she said. “I just get weary, though, because I’m very aware that there’s another human being around at the same time, and I’m klutzy, so I’ll trip. I’ll fall, which, I’m fine if it’s just me, but if there’s other people, I’m like, ‘Ahhh!’ Could be a disaster. But it’s fine. I’m just a bit of a worrier, but I’m OK.”
